Thresould decides how much voltage should set the digital output (D0) to HIGH stage.\n\n### LM35\n\n- Used to meassure environment temperature.\n- 3 pins: GND, VCC, and analog output (A0).\n- For every 1 centigrades of temperature, it outputs 10 milli-volts.\n\n```\nsensorValue / 1023 = temp / 500\ntemp = 0.488 * sensorValue\n```\n\n### DHT11 Module\n\n- Temperature and Humidity sensor.\n- DHT11 component needs pullup resistor, but the DHT11 module already has the built-in pullup resistor on the board.\n- Less accurate and slower than LM35. Outputs 1 times in a second. Useful for temperature 0-50 and humidity 20%-80%.\n\n### LCD 1602-I2C\n\n- Liquid Crystal Display\n\n### PIR Sensor\n\n- VCC, GND, and Analog output pings.\n- Two potentiometer to config delay and sensitivity.\n\n### LM393 Sound Sensor\n\n- It's a LM393 as described above, but instead of two sensor pins, it has a sound sensor built-in.\n\n### TCRT5000\n\n- Reflective optical color detection module.\n- Usually used for object detection, line tracking, and material detection.\n- Installed on a LM303 module.\n- On white surfaces it outputs 1023 (arduino), and 0 on black surfaces on the analog output.\n\n### L293D\n\n- Used to control the speed and direction of up to 2 DC motors.\n\n### Others\n\n- LED-RGB\n- Seven Segments (e.g. TM1637)\n- Dot Matrix\n- Tilt Switch\n- Active Buzzer: Black surface under the module. Use `digitalWrite` to set the pin to HIGH or LOW.\n- Passive Buzzer: Green surface under the module (you can see the board). Use `tone(pin, freq, duration)` to generate frequency for playing different musical notes.\n- Photoresistor\n- DC Motors\n- SG90 Servo Motors\n- BYJ48 Step Motors (4 Phase) + ULN2003A Driver\n- Ultrasonic Sensors\n- 74HC595 Shift Register\n- DS1302 Clock Module","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Favestura%2Felectronics","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Favestura%2Felectronics","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Favestura%2Felectronics/lists"}
